About heating bed - when it is needed

[Nathana]

Ambient temperature will affect the print in more ways than just warping on the bed, but I guess that's what she replied to, and not anything else, in true qu-db manner...
The basalt bed will not be so influenced by ambient temperatures due to the mass that is heated up, that is true. On the other hand they havent addressed people now starting to see that their basalt bed are cracked. But that isn´t good pr and now hidden in a forum no longer linked from their homepage, due to customer complaints on it...
why is there a setting to only cool layers down over a minimum size you think? because you need the heat to bond small layers together. Printing the stupid Qu-bd vase on the other hand has nothing to do with this, or the pain child of all qu-bd products = retraction of filament...
